2026 International Workshop on Performance, Portability, and Productivity in HPC
DescriptionThe Performance, Portability, and Productivity in HPC workshop aims to bring together developers and researchers with an interest in practical solutions, technologies, tools, and methodologies that enable the development of performance-portable applications across a diverse set of current and future high‑performance computers. The topic of Performance, Portability, and Productivity focuses on enabling applications and libraries to run across multiple architectures without significant impact on achieved performance and with the goal of maintaining developer productivity. This workshop provides a forum for discussions of successes and failures in tackling the compelling problems that lie at the intersection of performance, portability, and productivity in high-performance computing. This area touches on many aspects of HPC/AI software development and the workshop program is expected to reflect a wide range of experiences and perspectives, including those of compiler, language and runtime experts; applications developers and performance engineers; and domain scientists.
